I have a Myford Super 7 lathe and want to make a bush with a flange at one end from some 40mm round bar, and so hold this in a chuck and cut a 28mm hole through the centre with a boring bar.
The problem is, I want to pass the boring bar completely through the piece of bar but the centre hole of my 4" chuck is just 25mm
So does anyone know of a 4" or 5" chuck for the Super 7 which has a larger centre hole, as I have searched for another chuck but for some reason the manufacturers seem shy of providing the diameter of the centre hole?
I realise I could also hold the bar with a clamp on a faceplate (can't think of its name) but I want to do a number of procedures on this bush.
